Asphalt is known for its affordability and durability, and when properly maintained, it can also look great. However, if your pavement is showing signs of age, simple fixes like pothole repairs and crack filling might not be enough. In such cases, you have three primary options for pavement treatment: sealcoating, resurfacing, and replacement. Each option comes with its own set of costs and repairs. Deciding between asphalt resurfacing and replacement depends on the severity of the damage, and often, hiring a professional can help ensure you choose the best option.
Sealcoating: A Protective Layer for Longevity
Sealcoating is a protective liquid mixture that shields asphalt from damage caused by weather, UV rays, moisture, and oil leaks. Once applied, the thin layer creates a smooth, dark finish that not only improves the appearance of your pavement but also provides long-lasting protection. Regular sealcoating—typically every year or two—keeps your asphalt in top condition. Keep in mind, however, that sealcoating is best used for minor surface wear and doesn’t address larger issues like cracks or holes. Be sure to repair any damage before applying sealcoat.
Resurfacing: Restoring the Surface with an Overlay
Resurfacing involves laying a fresh layer of asphalt, or overlay, on top of the existing pavement. This cost-effective solution is ideal when your asphalt shows significant wear but is still structurally sound. Resurfacing can save you money compared to a full replacement, but it’s best used when the pavement has minor to moderate damage. If you notice areas with large cracks, water pooling, or significant surface deterioration, resurfacing may be the right choice. Before applying the new layer, necessary repairs like filling cracks, grinding uneven surfaces, and adjusting drainage features are required. Once everything is prepped, the new layer will leave your driveway looking like new.
Replacement: A Fresh Start
If sealcoating or resurfacing can’t restore your pavement to its original condition, replacement is the final solution. Repaving involves removing the existing asphalt down to the base layer, which is then leveled and compacted to ensure a solid foundation. After that, new asphalt is laid over the prepared subgrade, resulting in a brand-new surface. While replacement is more expensive than resurfacing, it’s the most effective way to address severe damage. With proper care, a newly repaved driveway or parking lot can last for many years.
